To ali /w-fmsu it may ooncern:

Be it known that we, FRANK E. VATTS .finti ilostfirn l. HASTINGS, citizens of the Unitefl States oi America, residing at De` 5 tioit, in the county of Wayne sind State ot Michignn, here invented certain new and useful lmprovenwnts in Speedometer-Drives for Vehicles, of which the following is 'a :ecicntioin reference being had therein to tno accompanying drawings.

The invention relates I'o speedometer irive n'ieolnxnisms of that type in which the tation of one of the steering wheels is nsmitted to the speedometer through a sible shaft transmission. lt is ueual with constructions to employ e bevel gear Lerinetliete' the Wheel and the flexitrein being mounted upon 1 or stub-er1le on wliieii the v f Vnl fle this lrnnolrle ie moved iti of tite wheel in steering` flexing ,if the .eli-aft wi'iili in lireilring. Thus the eiion ie winipnrntirely Short ect oi: tlie pres-nt invention to in Upon the transmission liy provimng Swivel connection Wlioli permits the turning of the knnekle witlioni i: Corresponding singulier movement of the sliet; and seeond by preferably loeating this sin alinenient with the exif;

ln the construction shown in l, the tiriven bevel gear wiieel E is mounted upon a shaft G, which is arranged in aline- .'tween the ment with line shank C of the knuckle. From this shaft motion is transmitted through bevel gear Wheels H to n transversely-arranged shaft, I direct-ly coupled with the flexible shaft F. By this uri-angeme-nt no movement of translation impartetl to the shaft G by .the turning of the knuckle, onl account of the axial alinenent of these parte, While lateral movement of the shaft. I is prevented by journaling the same in e bearing J, which has av swivel Conneom tion K to the knuckle. lt will therefore be apparent that the turning of the Steering Wheel will produce no effect upon the flexible shaft F, suoli as is ordinarily rodnced in speedometer clrivee.
